Imports
io.netty.util.internal.PlatformDependent
Implements Knuth-Morris-Pratt string search algorithm. Use static AbstractSearchProcessorFactory#newKmpSearchProcessorFactory to create an instance of this factory. Use KmpSearchProcessorFactory#newSearchProcessor to get an instance of io.netty.util.ByteProcessor implementation for performing the actual search.
